Overall, this is a solid and satisfying port of an older game that, while a little (okay, a lot) slow and slightly creaky, can still deliver a rich and meaty puzzle experience to be savored by adventure game lovers.

Still, Riven doesn't feel as definitive as other remastered adventures on iPhone and iPod touch. While the controls demonstrate an understanding of the devices, the inability to capitalise on the massive file size for a richer, higher resolution presentation is stunning in itself. Yet what Riven lacks in action, cutting-edge graphics and immediate appeal, it makes up for with a gripping plot and fiendishly captivating brain-teasers.
